They look fantastic! I don't think flowering will be any problem...if anything, the compactness will help the THC develop stronger because the nutrients don't have to travel as far up the plant stalk (if that makes sense).

If you wanted to, when it comes time to flower you can trim some of the top leaves so the leaves underneath get light too. But for outdoor grows, there is usually plenty of sun even for the leaves underneath. If you were doing an indoor grow, there might be cause for concern, but for an outdoor grow, you should be stoked :thumbsup:
